This map is the SPC's Probability for severe storms chart and as you can see, they have areas from Nashville eastward in the Day 4 outlook (Saturday) I'll continue to watch what happens with this map and also with the models, but here's the written outlook for Saturday too.
FOR DAY 4/SATURDAY...WITH THE COLD UPPER TROUGH FORECAST TO CONTINUE AMPLIFYING/CLOSING OFF OVER THE GREAT LAKES REGION...RELATIVELY STRONG WIND FIELDS IN THE MID LEVELS SHOULD DEVELOP AS FAR SOUTH AS THE CENTRAL APPALACHIANS. AHEAD OF THE EAST/SOUTHEAST ADVANCING COLD FRONT...A RISK FOR WIDESPREAD SEVERE TSTMS APPEARS LIKELY FOR MUCH OF THE OHIO VALLEY/CENTRAL APPALACHIANS INTO THE MID ATLANTIC/NORTHEAST STATES.
But for today, we look to stay mostly dry, BUT there could be one or two pop-up showers/t'showers today for northern areas of TN and southern sections of KY, but those chances are 10% at best. The bigger rain chances increase starting Friday and going into Saturday. Here's today's forecasted high's for these towns and areas.
Nashville: low 90's
Clarksville: low 90's; SLIM (5%) chance of a shower
Cookeville: mid 80's
Columbia: low 90's
Manchester: upper 80's to low 90's
